Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warning
light will not turn off even though the flat
tire is replaced with the spare tire. Re-
place the spare tire with the repaired tire
and adjust the proper tire inflation pressur-
e. The tire pressure warning light will turn
off after a few minutes.
CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).

Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light.For vehicles sold in U.S.A.
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful
interference, and (2) this device must
accept any interference received, includ-
ing interference that may cause unde-
sired operation.
NOTICE:
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are
designed to provide reasonable protec-
tion against harmful interference in a
residential installation. This equipment
generates, uses and can radiate radio
frequency energy and, if not installed
and used in accordance with the instruc-
tions, may cause harmful interference to
radio communications. However, there is
no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interfer-
ence to radio or television reception,
which can be determined by turning the
equipment off and on, the user is en-
couraged to try to correct the interfer-
ence by one or more of the following
measures:
Reorient or relocate the receiving an-
tenna.
Increase the separation between the
equipment and receiver.

154
Connect the equipment into an outlet
on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced
radio/TV technician for help.
FCC WARNING:
Changes or modifications not ex-
pressly approved by the party respon-
sible for compliance could void the
user’s authority to operate the equip-
ment.
For vehicles sold in Canada
Operation is subject to the following two
conditions:
(1) this device may not cause interfer-
ence, and (2) this device must accept
any interference, including interference
that may cause undesired operation of
the device.
REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered on the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After about 1
hour, the tire pressure warning light
comes on after blinking for 1 minute to
indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.

When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.
When changing the tire size.

155
To initialize the system, perform the fol-
lowing:1. Park the vehicle in a safe place and the hybrid system is off.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
434.)
3. Turn the “POWER” switch to “IG −ON”
mode.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for a few minutes with the “POW- ER” switch selected in “IG −ON” mode,
and then turn the hybrid system off.
If you push the tire pressure reset switch
while the vehicle is moving, initialization is
not performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.
25p124
If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
CAUTION
Do not push the reset switch without
first adjusting the tire inflation pres-
sure to the specified level. Otherwise,
the tire pressure warning light may
not come on even if the tire inflation
pressure is low, or it may come on
when the tire inflation pressure is ac-
tually normal.
